if that is the only trans code in the system without any circuit codes, then more than likely, the problem is internal and not in the solenoid block.
the P0733 DTC is a gear ratio error code. that means that the TCM is commanding the shift and the solenoid block is trying to make the shift.
usually when a solenoid block has an issue, it will throw a circuit or solenoid performance code.
how is the condition of the fluid? how many miles are on the car? any recent service work done recently?
